SHAFT ATTACHMENT FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 899,525 dated March 12,1889.

Application filed July 18, 1888.

To all who/n, may ounce/'11..-

Be it known that 1, DUNCAN DALLAS HARE, a citizen of the lfnited States,residing at Allegheny, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful lm glrovei'ncnts inShaft Attachments for Vehicles; and I do hereby declare the following tobe a full, clear, and exact description of the invention, referencebeing had to the accompanying drawings, which form part of thisspecification, in which Figure 1 is a perspective view of a two wheeledvehicle with my in'lprovement attached, and Fig. 3 a detail view.

This invention has relation toshal't attachments for vehicles, and ispart ieularly adapt ed for vehicles having two wheels-such'as roadcarts,dog-carts, cabs, gigs, and other vehicles of that type.

This invention has for its object to provide a two-wheeled vehicle withcertain attachments, whereby the horse motion is entirely obviated.

This invention has for its further object to provide means whereby theshafts are rendered adjustable vertically.

This invention has for its still further object to provide means wherebythe shafts may be widened or set farther apart.

This invention consists in an upright or standard bolted to the bottomof the vehiclebody and rising in the front thereof, said standard beingconstructed and designed to receive my improved shaft attachment.

This invention still further consists in a pair of spiral springsworking in opposite directions and attached to the upright standard andthe shafts.

This invention still. further consists in the novel construction,combination, and arrai'igement of parts, more fully described.hereinafter, and specifically pointed out in the claims.

A represents the body of the vehicle; a, the dashboard; B 3, thestandards or uprights, having a recess, 7) l), on both sides for thereception of the eye-lugs it" of the braces G G.

0 represent the shafts; c, the crossbar of same; D D, the springs; (Ithe supplementary spring; E the bolts passing throughthe springs an d ha vi n g screw-t breaded ends for the reception of the nuts e e.

Serial No. 280,289. (No model.)

5 1: F represent the blocks giving bearing to the bolts E E, and locatedabove and below 1' the braces G G. The braces G 4 are providedwitheyelugs 1' i, for the passage of the bolts through the standards.The recesses Y) Z)? are large enough to allow free movement of thebraces.

In riding in two-wheeled vehicles there is a constant dipping orup-and-dowu movement, which is very disagreeable to the occupants. Thismovement is caused by themetion of the horse, and is imparted to thevehicle through the shafts. My device overcomes this in the followingmanner: The braces which constitute part of the shafts are 1i ivot'all vattached to the standards and are allowed free movement, the springsretaining the shafts in their proper position and taking up the di'iping motion, being assisted by the supplementary springs situated onthe other side of the standard, these springs taking up the suddenreaction. Thus the vehicle will travel smoothly, the horse motion beingentirely overcome. In the downward motion the lower spring is compressedand the upper expanded, and vice versa.

I call particular attention to the nuts on the bolts impinging againstthe springs, as they not only limitthe movement of the springs, but alsoserve as means for regulating the shafts. For instance, when desiring tolower the shafts to suit the harness, the nut of the lower spring isturned against the spring, thus tightening the lower spring and at thesame time lowering the shafts. \Vhen it is found necessary to raise theshafts, the nut on the upper bolt is tightened and the lower oneloosened. The result is that the shafts are raised. By this means theshafts are adjustable to any desired angle or degree.

In vehicles of this type it is desirable to construct the shafts widerthan the body of the vehicle. I accomplish this by attaching the bracesto the cross-bar of the shafts as shown in Fig. 1 of the drawings.

Having described my invention, I do not. wish to limit myself to thisspecific construction, for the device may be reversed and the sameresult be obtained.

I am aware thatprior to my invention twoi wheeled vehicles have beenmanufactured 2. The combination, in a shaftattachment for two-WheeledVehicles, of a main spring and a supplementary spring setlongitudinallyone itlJOX'G and. the other below the shafts, substantially as shown anddescribed.

3. In a two-wheeled vehicle having pivotally-attached shafts andcross-bar, said bar 1 being wider than the vehicle-body, the eom- Zbination of the braces G G, with blocks F E,

located above and below said braces and giving bearing to the-bolts E E,said bolts pass ing through the standards B B and supportseams in gtheinain sprin D D, and supplementary spring (Z, all arrangedsubstantially as described.

4. In a two-\vl'ieeled vehicle having pivotally -attached shafts, thecombination, with the standards B B, having recesses 19 b for theeye-lugs h h, of the braces G G, bolts E E, passing longitudinallythrough the standards B B and bearing against blocks F F, springs D D,surrounding the bolts or rods E E of the sup idementary springs (Z cl,and nuts 6 e, impinging against said springs, substantially asdescribed, and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this7th day'of July, 1888.
